jdk_util_2 FAILED in Test_openjdk8_hs_sanity.openjdk_arm_linux

[smlambert]

These testcase failures have been reported during release triage, but a proper issue has not been raised, as they appear to eventually pass on rerun on some machines. Deep history shows these only passing on test-sxa-armv7l-ubuntu2004-odroid-2 which makes them problematic for release periods:
